IMPROVEMENT IN POTATO-DIGGERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern;

Be it known that I, WILLIAM J osnrgi, of Quincy, in the county of. Branch in the' State of Michigan, have invented a new and improved Potato-Digger; and I do hereby declare that the following is afull' and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of myinvcutiou consists in attaching to the frame of a common shovel-plow a blade made of two pieces of cast-steel plate, riveted together crossways, and formed so that it resembles a shovel-plow with a wing on each of the two sides. On the'back side project six or more steel rods, to separate the potatoes from the dirt, hereinafter more'fully'described.

To enable others skilled in the art to make and use my iuvention, 1 will proceed to describe its construction and operation, in which- The drawings are perspective views.

1 construct the frame of my potato-diggersimilar to that of the common shovel or corn-plow, with a beam, upright, and two handles, framed or bolted together, as at A. v r

My invention consists in the construction and arran ger'nent of the plow-blade.

The plates Zr and O O I make of steel, of the thickness generally used for cultivatorJtecth, which are riveted together at c e. l I

The plate I) is made nearly flat at the point for about two inches back, then gradually rises and forms an incline to the shank, where it is bolted to the frame The plate 0 G and back side of the plate I) are curved down a little, giving a slight convex surface on the upper or back part. The front edges of the plates are ground thin.

- On the backside I attach six or more round steel rods, as shown at d (l d.

One end of each is flattened and firmly riveted on the bottom side of the plate 0 0, (see at x.)

These rods serve to separate the dirt from the potatocs, and are made of sufficient size and strength to back side, leaving them on top of the ground.

The digger has proved itself (with one man and two horses) to do the work that would require six men.

I claim as new and desire to secure by Letters Iatentv The combination and arrangement of the plates Q and G O, the rods (Z d d, with the frame A, as herein described, and for the purpose set forth;

WM. JOSEPH.
